Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On March 27, 2017 (the “Effective Date”), Southcross Energy Partners GP, LLC (the “General Partner”), the general partner of Southcross Energy Partners, L.P., (the “Partnership”) approved separate contingent bonus agreements with a group of individuals which includes key employees, including each of Bruce A. Williamson, Brett M. Allan and Joel D. Moxley (each of whom is a named executive officer of the General Partner).

Under such bonus agreements, a form of which is attached hereto (the “Form of Bonus Agreement”), certain individuals and key employees of our General Partner (which includes our named executive officers), will be eligible to receive a cash bonus payment in the event of a Change of Control (as such term is defined in the Form of Bonus Agreement), so long as such employee remains employed by the General Partner as of the Change of Control. The amounts to be paid to such individuals and key employees will be determined by the board of the General Partner in its discretion, including factors as provided in the Form of Bonus Agreement. Accordingly it is not possible at the time of filing of this Form 8-K to determine the amount payable to participants, including the named executive officers listed above. However, the estimated aggregate payment to this group of individuals and key employees as a group pursuant to such contingent bonus agreements is estimated to be between four and eight million dollars and it is contemplated that any payment will be allocated in the ordinary course between the Partnership and Southcross Holdings LP.

The foregoing description of the Form of Bonus Agreement is qualified in its entirety by reference to the full text of the Form of Bonus Agreement, which is attached as Exhibit 10.1 to this Current Report and incorporated herein by reference.

Item 9.01 Financial Statements and Exhibits.
