On March 24, 2015, Midstates Petroleum Company, Inc. (“Midstates”)  and Midstates Petroleum Company LLC (“Midstates Sub”), a wholly owned subsidiary of Midstates, entered into a Sixth Amendment (the “Sixth Amendment”) to its Second Amended and Restated Credit Agreement dated as of June 8, 2012, among Midstates, Midstates Sub, as borrower, SunTrust Bank, N.A., as administrative agent, and the lenders and other parties thereto (the “Credit Agreement”). The Sixth Amendment provides that Midstates Sub’s borrowing base will remain at its current size of $525.0 million as part of the regular semi-annual borrowing base redetermination under the Credit Agreement. The Sixth Amendment also confirmed that the borrowing base will not be reduced as a result of the consummation of the sale of certain of its oil and gas properties in Beauregard and Calcasieu Parishes, Louisiana expected to close on or before April 30, 2015. The Sixth Amendment amends the required ratio of net consolidated indebtedness to EBITDA under the Credit Agreement for each of the fiscal quarters in 2015 from 4.0:1.0 to 4.5:1.0.  Additionally, the Sixth Amendment amends the mortgage requirements under the Credit Agreement to provide for an increase from 80% to 90% in the percentage of properties included in the borrowing base that are required to be subject to mortgages for the benefit of the lenders.

The foregoing description of the Sixth Amendment is a summary only and is qualified in its entirety by reference to the complete text of the Sixth Amendment, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

The information set forth under Item 1.01 concerning the Sixth Amendment is incorporated herein by reference.
