Explanation of Responses:

1. This Form 4 is being filed jointly by SemGroup Corporation ("SemGroup"), Rose Rock Midstream Holdings, LLC ("Holdings") and Rose Rock Midstream Corporation ("RRMC"). SemGroup directly owns 100% of the outstanding membership interests of Holdings. Holdings directly owns 100% of the issued and outstanding shares of common stock of RRMC. SemGroup may therefore be deemed to beneficially own securities of the Issuer owned directly by Holdings and RRMC and Holdings may therefore be deemed to beneficially own securities of the Issuer owned directly by RRMC.

2. In connection with the closing of the initial public offering of the Issuer, the Issuer granted the underwriters a 30-day option to purchase up to an additional 1,050,000 common units representing limited partner interests in the Issuer ("Common Units"). The 30-day option period expired on January 7, 2012 without the underwriters having exercised the option to purchase any of the additional Common Units. Therefore, pursuant to the Issuer's Second Amended and Restated Agreement of Limited Partnership, 1,050,000 Common Units were issued to Holdings as of such date.
