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

(c)    Appointment of Vice President, Chief Accounting Officer, and Controller

As previously reported, Paul F. Largess, age 65, advised that he intended to retire as vice president, chief accounting officer, and controller of Rose Rock Midstream GP, LLC (the “General Partner”) and SemGroup Corporation (“SemGroup”) on March 15, 2016. SemGroup is the corporate parent of the General Partner and the General Partner is the general partner of Rose Rock Midstream, L.P. (the “Partnership”). On February 23, 2016, the Board of Directors (the “Board”) of the General Partner appointed Thomas D. Sell, age 50, as vice president, chief accounting officer, and controller of the General Partner effective March 15, 2016. The Board of Directors of SemGroup Corporation (“SemGroup”) also appointed Mr. Sell to serve as vice president, chief accounting officer, and controller of SemGroup effective March 15, 2016.

From 1996 to 2016, Mr. Sell served in a variety of finance, accounting, and financial reporting roles for The Williams Companies, Inc. (“Williams”), an owner and operator of energy infrastructure in North America. Most recently, he served as staff vice president, enterprise accounting for Williams since 2013, as vice president of finance & accounting, midstream from 2008 to 2013, and as assistant controller from 2005 to 2008. From 1996 until its acquisition by Williams in 1998, Mr. Sell served as director, financial reporting for Mapco, Inc. From 1987 to 1996 he served in various staff and management audit roles for Deloitte & Touche.

Mr. Sell, like all officers of the General Partner, will be employed and compensated by a subsidiary of SemGroup, subject to reimbursement by the Partnership. He will also be eligible to participate in the General Partner’s equity incentive plan (the “Rose Rock Plan”). The portion of Mr. Sell’s compensation that will be payable by the Partnership includes (1) all of the expense of awards made to him under the Rose Rock Plan and (2) the amount allocated to the Partnership by SemGroup (and reimbursed to SemGroup by the Partnership), which is determined by the amount of time he actually spends working for the Partnership relative to the amount of time he spends working for SemGroup. See SemGroup’s current report on 8-K filed on February 29, 2016 (File No. 001-34736) for a description of Mr. Sell’s compensation by SemGroup.
